Motor Assembly - Lamb 1-Stage Ball Bearing with Thermostat (5.1") SEBO so a worn roller isThe Lamb 1 stage motor assembly (Part #119322 00) is a replacement 5. 1 inch ball bearing motor with a built in thermostat that powers your vacuum's suction system. The thermostat guards the windings by cutting power if the motor overheats, and the ball bearings support quiet, long running operation. A motor nearing the end of its life often loses suction, runs loud, overheats, or quits altogether, sometimes with a burning smell or heavy vibration.
